Abstract

PURPOSE:To obtain a chaff granulation apparatus capable of continuously performing collapsing and granulation with simplified drive mechanism, by connecting a crushing body and a granulator housing and allowing the rotary shaft of the transfer blade in the crushing body to continue to the revolution drive shaft of an extrusion roll. CONSTITUTION:When water is supplied from a water supply pipe 9 and chaff is supplied from a hopper 15 while transfer blades 3a are rotated, the chaff is allowed to tightly fill a crushing body 1 and a housing 4. When the chaff is further supplied, the compacted chaff is contacted with crushing blades 3b to be collapsed and again compressed, and this operation is repeated to crush the chaff. The crushed chaff is successively pushed in the housing 4 and extruded from a large number of small holes 50 by four extrusion rolls revolving while rotating on the surface of a die and the extrudate is cut by a scraping-off member 8 to be molded into pellets which are, in turn, discharged.

Description

DETAILED DESCRIPTION OF THE INVENTION 3. Detailed Description of the Invention The present invention relates to improvements in a rice husk granulating device for granulating rice husks into easily handled feed or fuel.

Since a-husks are difficult to rot and burn, it is difficult to dispose of them, and they are usually piled up in piles and left to burn over a long period of time before being disposed of.

In order to effectively utilize this rice husk, attempts have been made to compress it using a granulator, form it into granules, and use it as feed or fuel. However, the conventional rice husk granulation equipment simply used a conventionally known granulator and supplied rice husk to it, and if the rice husk was left as it was, it would easily crumble even if it was compressed and molded, so molasses A binder (binding agent) is added to increase the bonding strength, and the particles are formed into a predetermined shape. For this reason, the granulated rice husk becomes relatively expensive, and there is a problem in that the original purpose of effectively utilizing the rice husk as a waste product is lost.

For this reason, the applicant of the present invention has proposed that when rice husks are formed into rice husk pellets using a granulator, the rice husks are pulverized by a pulverizer and then supplied to the granulator. We have developed a means to reduce the amount of granules and to granulate them into granules of a predetermined shape without using a binder. However, this method requires the work of crushing the rice husks in advance, and also requires a crusher outside the granulator for the crushing process, resulting in the hassle of having to manage a series of operations. There is a problem that comes up.

The present invention was made to solve this problem, and by supplying unpulverized rice husks, the rice husks are efficiently crushed while being fed to the die of the granulator. It is an object of the present invention to provide a new rice husk granulation device in which a rice husk crusher and a rice husk granulator are integrally combined so that granulation is performed continuously.

In the present invention, for this purpose, a cylindrical crushing barrel is provided with a rice husk input port at one end and an open port at the other end, and is rotated by a rotating shaft to remove rice husks. A die is provided with a transport material to be transferred to the other end and a fixed crushing blade protruding from the inner circumferential surface of the crushing cylinder, and a die having a large number of extrusion holes in the housing at the open mouth on the other end of the crushing cylinder. The present invention proposes a rice husk granulation device in which a receiving port of a granulator is connected and connected to an extrusion roll that rotates and revolves on the surface of the rice husk granulator. In the granulation device, a rotating shaft of the transported material provided in the crushing cylinder is extended from the receiving port of the granulator into the housing of the granulator, and the extended shaft is integrally or integrally connected to the revolution drive shaft of the extrusion roll. The present invention proposes a rice husk granulation device that is made up of continuous rice husk granulation equipment.

When an appropriate amount of water is supplied from the water supply pipe 9 and fed into the rice husk crushing drum 1 from the supply hopper 15 through the inlet 11, the rice husks are driven into the crushed waste l by the drive of the motor M (usually around 20 HP). into the casing 4 of the granulator a, which is integrally continuous with the crushed waste 1, by the transported material 3a, which is slowly rotated by the rotating shaft 2 (about several times per minute to several times per minute). The die 5 installed in the housing 4 is pushed toward the
The crushed debris 1 is tightly packed into the casing 4 from the front of the die 5 to the input port 11 for the crushed debris 1. In this state, the rice husks that are continuously supplied from the supply hopper 15 side through the input port 11 are further pushed strongly by the transport material 3a, so that the rice husks located in the crushed waste 1 are is the rotation axis 2
This cylindrical rice husk is compressed into a single cylindrical body that tightly fills the gap between the crushed waste 1 and the trunk peripheral wall 10 and rotates together with the transported material 3a... By repeating the operation of being broken in contact with the fixed crushing blade 3b, compressed and compacted again, the rice husk is gradually crushed by the strong friction between the rice husks, and the rice husk is in a state where it has received the crushing. As a result, they are successively pushed into the casing 4 of the granulator a, and within the casing 4, the extrusion roll 6 located in front of the die 5 presses the extrusion hole 50 of the die 5.
